Blockchain technology is no longer a niche innovation — it’s reshaping how we interact with finance, data, and digital ownership. With over 300 million users worldwide, its influence spans from decentralized finance platforms to enterprise solutions in healthcare and supply chain management.
In 2025, the blockchain landscape is undergoing a significant transformation. Ethereum, long considered the cornerstone of decentralized applications, is now facing formidable competition from platforms like Solana and Avalanche. But who will come out on top?
Below, we compare these blockchains as of April 2025 across key areas — including developer adoption, ecosystem growth, transaction speeds, fees, security, and roadmaps — to assess their current standings.
Developer Adoption and Ecosystem Growth
Healthy developer communities and rich ecosystems signal a blockchain’s long-term potential. Let’s look at how Ethereum, Solana, and Avalanche compare in scale of development, major projects, and overall growth.
Ethereum Ecosystem Size
Ethereum remains the largest blockchain ecosystem, maintaining leadership in decentralized finance. As of April 2025, Ethereum’s total value locked (TVL) stands at approximately $92.21 billion, representing over 52% of the DeFi market. Over 5,189 ERC-20 tokens are developed on Ethereum, showcasing significant network utilization.
By the end of 2024, Ethereum had attracted the largest number of developers in the blockchain space. According to DeveloperReport, as of November 2024, it had around 6,244 total monthly active developers. This figure reflects a plateau or slight decline compared to the 2022 peak, suggesting a stabilization of developer engagement rather than a drop-off.
Solana Ecosystem Size
The Solana network has earned a reputation as the premier blockchain for memecoin launches, thanks to its low transaction costs, high transaction speeds, and user-friendly infrastructure. It has even been used to issue “official memecoins” linked to figures like U.S. President Donald Trump and the controversial Argentine token, Libra.
A wave of speculative trading pushed daily trading volume to a peak of $57.65 million in January 2025. By April 2025, that figure declined to $39.91 million. According to Zach Pandl, Head of Research at Grayscale, this suggests the end of the initial hype may be fading.
Although Solana’s DeFi total value locked has been volatile — declining from $11.83 billion at the start of 2025 to around $6.5 billion by April 2025 — its developer base has remained relatively stable. After reaching a peak of approximately 3,584 monthly active developers in June 2022, the number slightly declined to about 3,201 by the end of 2024, indicating sustained developer interest despite market fluctuations.
Avalanche Ecosystem Size
Though smaller in scale compared to Ethereum and Solana, Avalanche is steadily gaining ground through its specialized subnet architecture. With a DeFi TVL of approximately $1.5 billion and over 400 monthly active developers, the network is attracting consistent engagement — particularly in areas like gaming, enterprise solutions, and institutional applications. Its flexible subnet model enables the creation of application-specific blockchains, fostering innovation in sectors such as GameFi and regulated finance.
| Metric | Ethereum | Solana | Avalanche |
| TVL (April 2025) | $92.21B | $6.5B | $1.5B |
| Market Share (DeFi) | ~52% | ~7% | ~1.3% |
| Monthly Active Developers | ~6,244 | ~3,200 | ~400 |
| Token Standard / Features | ERC-20 | SPL | Subnets |
Ethereum, Solana, Avalanche: Comparing Transaction Speeds and Fees
Scalability and fees significantly impact user adoption across Ethereum, Solana, and Avalanche. Each blockchain tackles these challenges differently, influencing their real-world usability and appeal to developers.
Ethereum: Leveraging Layer-2s to Boost Throughput and Reduce Costs
Despite Ethereum’s transition to Proof-of-Stake, its base layer still processes around 15.96 transactions per second (tx/s) as of April 21, 2025, with a theoretical maximum of 119.1 tx/s. To address scalability, Ethereum has adopted a modular approach centered on Layer-2 rollups such as Arbitrum, Optimism, and zkSync —networks that significantly boost throughput while preserving the chain’s decentralization and security.
Today, a substantial portion of Ethereum’s activity has migrated to these rollups. As of April 22 2025, the average gas fee on Ethereum’s mainnet was $0.3702, whereas Layer-2 fees were far lower — just $0.0127 on Arbitrum and $0.0162 on Base.
Looking ahead, Ethereum’s next major upgrade, Pectra, scheduled for May 7, 2025, will merge the execution and consensus layers and implement 11 EIPs designed to enhance scalability and transaction efficiency.
In short, Ethereum’s scalability challenges have been largely addressed through Layer-2 innovation — though its base layer remains slower and more expensive compared to Solana and Avalanche.
Solana: Ultra-Fast Transactions and Minimal Fees
Solana prioritizes high throughput and minimal fees through its unique combination of Proof of History and Proof-of-Stake consensus. While the network is theoretically capable of processing up to 65,000 transactions per second (TPS), it consistently sustains around 1,144 TPS in practice. With average block times of just 400 milliseconds and near-instant transaction finality, Solana delivers one of the fastest user experiences in the blockchain space.
Transaction fees are the lowest among the three blockchains analyzed, averaging only $0.0035 over the past month, making Solana ideal for microtransactions, gaming, and high-frequency DeFi trading.
Importantly, Solana’s infrastructure has become significantly more stable since earlier outages. The upcoming Firedancer validator client, currently in testing, has demonstrated the ability to handle over 1 million TPS in synthetic benchmarks—a milestone that signals major advancements in both performance and network decentralization.
Avalanche: High-Speed Finality with Subnet Scalability
Avalanche sets itself apart through parallel scalability enabled by its unique subnet architecture—customizable, independent chains with their own performance and fee structures. While the Avalanche C-Chain theoretically supports up to 1,191 transactions per second (tx/s), actual usage is typically lower; as of this writing, it averages around 4.8 tx/s. However, the network’s true strength lies in its ability to horizontally scale through subnets, distributing activity efficiently across a growing ecosystem.
By late 2024, Avalanche’s “Pulsar” subnet alone was contributing significantly to daily transaction volumes, underscoring the model’s scalability potential.
Avalanche also achieves impressively fast finality, typically under one second on the C-Chain, surpassing Ethereum’s 12-second block times and rivaling Solana’s near-instant confirmation speeds. Already known for modest fees, Avalanche saw further cost reductions following the April launch of the Octane upgrade, which introduced a dynamic fee mechanism that adjusts pricing based on network demand. As of this writing, the average transaction fee stood at $0.0179, making it the second most cost-effective platform among the three.
Overall, Avalanche delivers strong performance, low and predictable fees, and flexible scaling through its subnet model. While no individual subnet yet rivals Solana’s raw TPS output, Avalanche’s horizontally scalable infrastructure positions it well for sustained future growth.
| Metric | Ethereum (Mainnet) | Solana | Avalanche (C-Chain) |
| Theoretical TPS | 119.1 | 65,000 | 1,191 |
| Practical TPS | 15.96 | 1,144 | 4.8 |
| Average Block Time | 12.08s | 0.39s | 1.3s |
| Avg. Transaction Fee (30 days) | $0.3702 | $0.0035 | $0.0179 |
| Scalability Approach | Layer-2 rollups | Monolithic | Subnets |
Security vs. Decentralization: How Ethereum, Solana, and Avalanche Balance Trade-offs
Security, decentralization, and performance often involve trade-offs, improving one aspect typically causes sacrificing at least one of the other two. Ethereum, Solana, and Avalanche illustrate three distinct strategies.
Ethereum: Prioritizing Decentralization and Security
Ethereum is widely viewed as the most decentralized smart-contract blockchain, boasting over 1,063,960 global validators. This large validator base enhances security and resistance to censorship. Ethereum’s security is battle-tested, maintaining an uninterrupted record since its 2015 launch, which makes it a trusted settlement layer for high-value transactions.
However, Ethereum’s decentralization is being challenged by the growing dominance of pools like Lido and centralized exchanges. These entities control a large share of staked ETH, concentrating power in the hands of just a few players. As of February 2024, Ethereum’s Nakamoto coefficient — a metric that measures how many independent entities are needed to compromise the network — was estimated to be as low as 2–3, indicating a high degree of centralization risk.
In response to these concerns, the Ethereum community has been actively exploring ways to promote more decentralized alternatives. Efforts include encouraging the use of diverse pools and supporting the development of decentralized protocols to distribute power more evenly across the network.
As of April 2025, Ethereum no longer appears on Nakaflow.io, a platform that provides data on the Nakamoto Coefficient for various blockchains, which may be related to changes in the methodology for assessing decentralization or challenges in obtaining transparent data on ng distribution within the network.
Notably, in March 2025, an X user known as Adidust.eth (@dustdust213) estimated Ethereum’s Nakamoto Coefficient to be 41, suggesting a significant improvement in decentralization.
Solana: Speed at the Cost of Some Decentralization
Solana offers superior performance through its Proof-of-History and PoS mechanisms, achieving thousands of transactions per second. Yet, it does so by relying on fewer, high-performance validators in the mainnet — about 1,300 globally — making it more centralized than Ethereum. Its Nakamoto coefficient is at 20 as of 2025, a strong metric among PoS chains but reveals stake concentration in fewer hands.
Security-wise, Solana’s ledger remains cryptographically secure, but past network outages have raised concerns over reliability. The Solana network experienced several major disruptions in 2021–2022, including a 17-hour outage in September 2021 caused by a surge of bot activity during a token launch, and additional outages in January and October 2022 due to transaction spam and validator issues. However, by late 2024, stability had improved significantly. This progress is supported by ongoing efforts to strengthen the network, such as the development of a second independent validator client, Firedancer, by Jump Crypto, which aims to boost both performance and decentralization.
Solana continues to trade off some decentralization in favor of unmatched speed and throughput, making it suitable for most real-world use cases. At the same time, the community remains focused on improving validator diversity and decentralizing stake distribution to mitigate centralization risks.
Avalanche: Balancing Decentralization, Security, and Flexibility
As of Q2 2025, Avalanche is gaining renewed momentum in the Layer 1 ecosystem by positioning itself between Ethereum’s high decentralization and Solana’s speed-focused architecture. With roughly 1,500 validators and a Nakamoto coefficient of 25, signaling meaningful, though not maximal, decentralization relative to its performance capabilities.
The December 2024 Etna upgrade, part of the broader Avalanche9000 initiative, marked a pivotal shift. It eliminated the requirement to stake 2,000 AVAX to launch a custom subnet. Developers can now deploy Avalanche Layer 1s with minimal capital, streamlining the path to launching sovereign blockchains.
Notably, Geoffrey Kendrick, global head of digital assets research at Standard Chartered, praised Avalanche’s scaling strategy, especially after the recent Etna upgrade. Kendrick noted early success: about 25% of active subnets are Etna-compatible, and developer participation has surged by 40%. Some developers are even shifting from Ethereum Layer 2s to Avalanche, drawn by its Ethereum-friendly architecture.
Blockchain Roadmaps 2025: Ethereum, Solana, and Avalanche Chart Their Next Moves
2025 forces blockchain networks to pursue ambitious roadmaps focused on scalability, decentralization, and mainstream adoption.
Ethereum: Advancing Toward Full Danksharding
Ethereum’s evolution is guided by a flexible roadmap shaped through open research, community collaboration, and real-time technological needs. Unlike traditional software projects with fixed timelines, Ethereum upgrades are iterative and designed to address both immediate challenges and long-term scalability.
The next major milestone is the Pectra upgrade, scheduled for May 7, 2025. This hard fork merges the Prague execution layer with the Electra consensus layer and introduces 11 Ethereum Improvement Proposals aimed at improving scalability, account abstraction, and validator operations. It builds on the momentum of the Dencun upgrade (March 2024), which implemented proto-danksharding (EIP-4844) to significantly reduce Layer-2 rollup costs by introducing “blobs” for more efficient data storage.
The Ethereum roadmap, initially outlined by Vitalik Buterin, is grouped into several architectural categories. The Ethereum team uses simpler, user-centric language to describe these key developments:
- Pectra. Makes Ethereum easier to use, faster, and cheaper by changing how accounts work.
- Danksharding. Reduces fees on Layer 2 by adding extra data (“blobs”) to blocks.
- Staking withdrawals. Lets users easily unlock ETH they staked.
- Single slot Finality. Makes transactions confirm almost instantly instead of waiting several minutes.
- Proposer-builder separation. Splits block creation tasks among different validators to make Ethereum fairer and harder to censor.
- Secret leader election. Protects validators by hiding who creates the next block, preventing targeted attacks.
- Account abstraction. Supports easier-to-use smart contract wallets directly in Ethereum.
- Verkle trees. Enables very lightweight nodes (“stateless clients”) that can verify transactions without storing lots of data.
- Statelessness. Lets users run nodes easily without needing large amounts of storage, greatly reducing costs.
Importantly, Ethereum’s roadmap is a living framework. From blob-based scalability to stateless node design, Ethereum is not just scaling, it’s rearchitecting itself for the decentralized future.
Solana: Enhancing Stability and Throughput with Firedancer
Solana has entered a transformative phase, focusing on scalability, decentralization, and real-world utility. The ecosystem has matured with products like Solana Pay and the Saga smartphone, while developer activity remains among the highest in the blockchain space.
At the core of Solana’s technical evolution is Firedancer, a new validator client developed by Jump Crypto. Currently in testing, Firedancer has demonstrated the ability to process over one million transactions per second, significantly improving performance, minimizing single-client risk, and enhancing overall network reliability.
Solana is also implementing several protocol-level upgrades:
- A new consensus algorithm is in development that will eliminate vote transactions, improving both finality and block times.
- Efforts to double block space by increasing compute unit limits (from 48 to 60 million CUs) are currently on testnet, enabling higher throughput.
- Enhancements such as QUIC packet ingestion, localized fee markets, and reduced node hardware requirements are improving both stability and validator decentralization.
In terms of vision, Solana is uniting around IBRL (Intra-Block Reactive Latency)—a conceptual North Star for sub-second latency that aligns the entire ecosystem around low-latency performance goals.
On the privacy front, confidential transfers have been introduced, making Solana more appealing to institutional users requiring private transactions. Projects like Helix’s RPS 2.0, which decouples read and write layers, further strengthen the architecture.
Institutional engagement is also evolving. Solana is seeing a shift from speculative interest to real-world integration, with organizations exploring how to build on Solana rather than merely investing in it. The creation of the Solana Policy Institute highlights this shift, ensuring the protocol has a voice in regulatory discussions.
The Accelerate event (May 19–26, 2025) and the annual Breakpoint conference will showcase Solana’s advancements, including possible innovations like Solana-native rollups.
As Solana continues to push boundaries in throughput, reliability, and usability, it is increasingly viewed as a peer to Ethereum in the race to dominate the decentralized application space.
Avalanche: Scaling Through Subnet Expansion
Avalanche continues to scale through subnets—custom, application-specific chains that now operate as Layer 1 networks, offering teams greater flexibility and sovereignty. Recent gas fee reductions on the C-Chain and for subnet deployment have significantly lowered the barrier to entry, accelerating adoption across sectors like GameFi, DeFi, and enterprise solutions. Notable implementations include Shrapnel, a AAA game, and institutional subnets using the Avalanche Evergreen framework.
Avalanche’s roadmap for 2025 introduces several key initiatives:
- The Etna upgrade enhances network performance and efficiency.
- The Avalanche9000 campaign drives global outreach and blockchain adoption.
- A rebranding of subnets as Avalanche L1 reinforces their positioning as standalone, high-performance chains.
- The launch of build.avax.network, a new developer platform, empowers builders with tools and documentation.
- A Multi Grants Program supports innovation within the ecosystem.
Avalanche is also pushing the frontier of AI integration. With the launch of Avalanche Network 3.0, the platform targets sub-second finality and enhanced throughput. Through initiatives like the $100 million infraBUIDL(AI) fund and support for Kite AI, Avalanche is embedding artificial intelligence into blockchain infrastructure to boost scalability and data processing.
On the interoperability front, Avalanche Warp Messaging enables cross-subnet communication, while continued improvements in protocol design aim to deliver a unified multi-chain experience. Developers benefit from HyperSDK, a framework for building high-performance virtual machines tailored for specialized use cases such as NFT minting, AI apps, or order book trading.
Complementing its tech innovations, Avalanche is expanding blockchain education initiatives globally and regionally to foster awareness and grow the community.
